I think you don’t depend on those committing espionage to filter anything. Mostly those kind of people in the past were in prison or found dead of natural causes.
I just want to know where you think the line is. While you claim not to trust the spies to redact this, remember the US government refused to redact and release any of it, though, if you knew of its existence, you could make a FOIA request for exactly this and the government would have to comply (if you had knowledge of the documents you wanted access to).
